Why passenger planes there are no parachutes

Fasten your seat belt, put on your life jacket, don't forget the oxygen mask. On these safety measures everyone knows who has ever been on a plane.

And everyone will certainly wonder: what would happen if the plane goes down? Well, if in water there are life jackets come in handy. And if you just on the ground? Where is the parachute? Why not give the parachute? Because so many lives could have been saved in all these disasters.

Aviation experts unanimously repeat that the parachute in the plane is unnecessary, expensive and generally out of science fiction. But aerophoba don't give up: they believe that the parachutes can be installed on the plane, if you add more money for the ticket, to use the best engineering minds in the country, and indeed in military jet aircraft is already there!

There is even a parachute with which it is possible to successfully jump from the 7th floor. So why not install a parachute or flying off the capsule on the plane? "Restore" all figured out.

A parachute in a passenger plane just once. Let me explain why:

1. Passenger plane — a highly reliable machine;

2. Most accidents with passenger aircraft going on takeoff and landing, that is the minimum altitude when the parachute is just useless (he can't open up);

3. When flying at flight level, i.e. the estimated height of 10-11 thousand meters, the parachute is also useless: the man left the plane and just die. After all, "outside" temperature is -40 degrees, thin atmosphere and almost no oxygen;

4. Finally, to carry, imagine a set of parachutes for 300-500 people is a lot of excess weight and little space. Be nowhere to put Luggage happy tourists.

5. And most importantly: do not carry parachutes in order to safety of the passengers. The turbulence (turbulence), even the most insignificant, part of the suspicious passengers pohvatali these same parachutes and run with them to the exit in an attempt to open the door.

And so — no parachute — no worries! Happy flying!
Ah Yes, the capsule is the area of science fiction. For military aircraft this is true when you have to save one or two people. For a large number of passengers is unrealistic. It is very expensive, but it's not even the cost, but the fact that it is very difficult to implement in technical terms. Because the ejection seat of a fighter is the most complex mechanism, like a small rocket with a complex system for survival.

And yet for each person — if the passenger version — you need to include a hole in the fuselage and the hull where all this "capsule" will fly. And the fuselage and the covering of the modern passenger aircraft is a very durable design that eliminates any voids or holes, and are able to withstand the aerodynamic, weight, and thermal loads when flying at speeds around 900 km/h.

Why you need a parachute, if it is not possible to use it?

On military aircraft (fighters) have parachutes, but it's not just the parachutes, and the whole rescue system. The system includes an ejection seat, oxygen system, parachute system and a protection system against mechanical damage of the person incident flow.

Weighs the whole thing together in about half a ton. To talk about how this system works, I think, does not make sense, because it would take about 20 pages of A4.

It is known that the overwhelming majority of accidents occur on takeoff and landing. So: use just a parachute in a passenger plane do not work, because it (the plane) flying very high and very fast.

The passenger under any circumstances will not be able to wear a parachute in the cabin, happened, much less leave the plane.

To open the doors to the plane at an altitude of 10-12 km will have the plane to depressurize, that is, to let out all the air, otherwise the door is not open. And if you do, as in a fighter (when the door "shot"), there will be explosive decompression, and this, in turn, instant death.

In the fighter pilot sits in a protective helmet and oxygen mask, and when you activate the rescue system oxygen system begins to pump air into the lungs under positive pressure (immediately), which ensures the functioning of the organism.

Understand that these seats in the passenger compartment are excluded.

Next. The plane flies at a speed of about 800-900 km per hour, and this means that to emerge unharmed from a plane at that speed — utopia. The person together with his parachute could be ripped to shreds by the oncoming air flow.

The fighter recovery system ensures the safety of the human body by entering in the incoming flow special vent. It's such a telescopic steel rod that are shot and recorded in front of the body and the head of the pilot.

So, this deflector splits the incoming stream and saves the whole human body. Also, do not forget that a military pilot is in protective helmet.

Next. Even if set in civil aircraft like military aircraft recovery system, the number of passengers that will be able to carry the aircraft will be reduced by approximately 4-5 times, this means that the ticket will cost the same number of times more expensive.

Are there many passengers willing to fly from Moscow to Sochi for 100 000 in one end? Yes, and to be in an ejection seat should strapped and pulled tight, the helmet and oxygen mask!

And, perhaps most importantly. Fly is not only young girls and guys are absolutely the type of sport and healthy of children, the elderly, hypertensive patients, which is not something that the bailout will not survive physically, but even the atmospheric pressure decrease below a certain level for them may be deadly?

The use of a parachute in the classical sense (the jetpack on the back) is impossible by definition: you're not going to make every passenger wear the backpack on your back and sit in the plane for 3-15 hours? And run jump can not 99.9% of the people in the plane. They just never did.

As for the rescue parachute of the cabin. At low altitude, during takeoff and landing, just not enough height and time to use the system. And the collision of two airplanes, you know, already on the drum all these parachute devices.

And echelon to be in the plane, even with a failed engine, much safer than to leave the plane (well, we already mentioned above that this is science fiction, out of the plane at an altitude of 10 km).

Is it possible technically to take a parachute with you?

If you still decided to take a parachute with you, ban you, no one can. Laugh shouldn't either.

"The parachute is the same thing as everything else. If by weight, it passes as hand Luggage, no problems will arise, you can take on Board. Specific weight rules better to check in advance the airline", — said the "Restoree" in help service of the airport "Sheremetyevo".

But still take a trip the parachute is just in case if you really want to scare the other passengers, especially impressionable aerophoba. To use the parachute on purpose still does not work, sure our expert.

So just fasten your seat belt, sit back in your chair and think about something pleasant. And from the window almost always offers fantastic views. Have a nice flight and soft landing! published
